Bio‐Inspired Multimodal Hardware Front‐End Enabled by 2D Floating‐Gate Memory for UAV Perception

Advanced Functional Materials, EarlyView.
A MoS2/h‐BN /graphene floating‐gate memory underpins a bio‐inspired multimodal front end that integrates visual, inertial, and airflow cues. A 4 × 4 FG memory array encodes temporal intensity differences, while IMU‐ and airflow‐driven threshold modulation suppresses self‐motion artifacts, enabling fast, low‐power, robust autonomous UAV tracking and ...

LL‐37 Driven Phase Transition and Stacking in Oligolamellar Gram‐Negative Bacterial Membrane Models

Advanced Functional Materials, EarlyView.
This work establishes oligolamellar bacterial membrane models to investigate how LL‐37 disrupts the complex dual‐bilayer architecture of Gram‐negative bacteria. Combining SAXS, cryo‐TEM, electrophoretic mobility measurements, and coarse‐grained simulations, it reveals cardiolipin‐driven phase transitions leading to bicelle‐like structures and membrane ...
